Fats as a whole should provide no more than the third part of total daily calories, and saturated fats should make up no more than 10 percent. Cholesterol should not be eaten every day over what is contained in one egg yolk, which is about 300 mg.
Saturated fats are harmful because they raise, as any other nutrient, levels of cholesterol. These are mostly found in red meat.
Some unsaturated fats can give the body a number of benefits. Vegetable products and fish are most contain such fats.
Intake of monounsaturated and polyunsaturated fats can reduce blood levels of bad cholesterol or low density (LDL). Corn oil is rich in polyunsaturated fat.
Monounsaturated fats tend to lower bad cholesterol only. Foods that contain oil are olive, canola, sunflower and maize, in that order of preference.
Eat fish twice a week to prevent heart disease.
